Name
Function
LED1
Power indicator
(Green)
This indicator is on when the expansion card is
powered on.
LED3
Communication
indicator (Green)
This indicator is on when the expansion card is
establishing a connection with the control board; it
blinks periodically after the expansion card is properly
connected to the control board (the period is 1s, on for
0.5s, and off for the other 0.5s); and it is off when the
expansion card is disconnected from the control board.
LED4
Error indicator (Red)
This indicator blinks when an error occurs (the blinking
period is 1s, on for 0.5s, and off for the other 0.5s). You
can query the error types on the upper computer Auto
Station.
This indicator is off when there is no error.
LED5
Power indicator
This indicator is on when the expansion card is
powered on.
LED6
RUN indicator (Green)
This indicator is on when the PLC program is running; it
is off when the PLC program stops.
The EC-PC502-00 programmable expansion card can replace some micro PLC applications. It
adopts the global mainstream development environment PLC, supporting the instruction
language (IL), ladder diagram (LD), and sequential function chart (SFC). It provides a user
program storage space of 16K steps and data storage space of 8K words, and supports saving
data of 1K words at power failure, which facilitate customers' secondary development and
meets the customization requirements.
The EC-PC502-00 programmable expansion card provides 6 digital inputs, 2 relay outputs, 1
analog input, 1 analog output, 1 RS485 communication channel (supports master/slave
switchover). It is user-friendly, providing relay outputs through European-type screw terminals
and other inputs and outputs through spring terminals.
